I am an industrial worker during the War of Resistance

Chapter 38 ZB26 Czech Light Machine Gun Barrel
In the machinery manufacturing plant, the main body of a cast hydraulic press, shaped like a large C, stands upright in a processing area of ​​the workshop.

However, its back is straight, and the probe on top is also straight.

Below is a U-shaped base with an opening facing forward.

The hydraulic press has a large opening at the top and bottom that is over 1.5 meters wide.

The machine body is smaller at the top and larger at the bottom, which makes the center of gravity of the hydraulic press more stable.

On the protruding crossbeam above, there is a pre-machined circular hole, which is the location for installing the hydraulic cylinder.

The hydraulic press parts, which have already been processed, were ready long ago.

They're already on the cart lined with cork boards.

The hydraulic rod protruding from the hydraulic cylinder is ten centimeters in diameter, as thick as the column of the forging press, and it is now fully assembled.

These were all done by Chen Changzai's students.

From the initial straightening and chemical plating of the inner cylinder of the hydraulic cylinder to the external plating of the hydraulic rod.

Next comes the installation of the hydraulic piston and piston rings.

Installation of brass support frame sealing sleeve and outer sealing frame sealing ring.

And the final sealing and molding.

All of these were completed by Chen Changzai's students.

How many students does he have now?

Chen Changzai sometimes couldn't remember.

Anyway, it's been from the very beginning of burning sulfuric acid to make explosives until now.

Every time he starts a new project, he brings along a group of students.

From the initial thirty or forty people, to the current batch of fifty or sixty people learning from him.

From chemistry to physics to mechanical manufacturing, there have been hundreds of people involved.

Chen Changzai taught his students based on their actual circumstances.

Since the headquarters brought back a lot of science textbooks.

Although he did not go to teach at the science and technology school at headquarters.

However, whenever there are students over there who excel in their studies and have exceptional talent, the headquarters will send them to Chen Changzai's side immediately.

This will allow students to connect theory with practice and prevent them from becoming bookworms.

Chen Changzai would lead the students in work during the day and give them theoretical lessons at night.

Now, when Chen Changzai is giving theory lectures, he is no longer the same as he was at the beginning.

Because there are no textbook guidelines, but rather the logical line of what he wants to achieve.

Sometimes, as we're talking, we lose track of which branch of the conversation we've taken.

This teaching method is indeed very helpful for developing divergent thinking.

But that's only for students with an extremely solid foundation.

In later generations, it would be something that could only be used when lecturing to master's students.

His current students, apart from a few with exceptionally extraordinary talent, are mostly confused by what he says.

Later, with the advent of systematic textbooks, Chen Chang was able to maintain the main theme when lecturing.

It won't go too far off-topic.

This way, more of his students can keep up with his way of thinking.

Although Chen Changzai was both working and teaching students.

But he himself never stopped learning.

In addition to those textbooks, he also needed to review, understand, and read them in depth.

The comrades of the Special Branch painstakingly brought back those German and English science textbooks and reading materials.

He never put it aside.

In later years, he served as a senior engineer, chief engineer of a military factory, and vice president of production management.

If you don't know a few foreign languages ​​or can't read foreign technical documents.

Then none of the engineers below will even give you a second glance.

In particular, the technological level of the English and German-speaking regions is relatively high, placing them at the forefront of international technology.

Do you really think being a technically skilled leader is so easy?

In the tech industry, nothing else matters; you have to show concrete results.

If you want to gain an advantage over others, you must have the technical skills to do so.

You can't get ahead in the tech industry just by flattering people.

Imagine this: at a technical seminar attended by a high-ranking leader, someone below, who is dissatisfied with you, suddenly starts asking you a few technical questions from abroad in a discussion-style tone.

When you're stammering and can't answer, the other person tells you the answer.

Do you think you can still hold onto your positions as chief engineer and vice president of production?

A high-ranking leader may have many problems, but a fool will never be able to sit in that important position.

They all know what their foundation is.

Those who didn't know have already been eliminated.

Therefore, in order to keep her position and be able to climb to a higher position in the future, Chen Changzai in later generations...

He put in a lot of hard work on several major foreign languages, especially English and German, which are specialized technical languages.

He was able to communicate with technical experts from those countries almost entirely without the need for a translator.

Because none of those translators could understand the technical language as accurately as he could.

It's important to understand that phonetic characters and ideographic characters are two completely different concepts.

As Chinese is a logographic language, if you know a few thousand Chinese characters, you can combine them at will to understand the documents or materials you want to read.

But this doesn't work for phonetic characters.

Whether it's English or German, they create new words every year.

Data shows that the number of English words is increasing by 15,000 per year.

With this kind of growth method, even if you brought Einstein to the future, he would still be just an illiterate person.

Even under those circumstances, Chen Changzai could understand technical documents in English and German, let alone now, with such simple English and German documents.

After another round of learning and understanding of more fundamental science knowledge.

Some things that were buried deep in his mind and almost forgotten resurfaced in his mind.

To reduce energy consumption, the brain tends to hide things that are not frequently used deep inside.

Sometimes you can't find it even if you want to.

Now he's dug all these things out again.

Then, he taught his students the experience he had gained through most of his life's work.

This has a consequence.

His highly talented students made rapid progress when they studied under him.

Those who are less talented will find it difficult to keep up with his way of thinking.

Even so, those who are progressing slowly are still much faster than the students studying at the headquarters science school.

After all, those who can come to his side are not all geniuses.

Those are all extremely talented.

Watching his students, whom he had only recently started training, already getting the hydraulic press pretty much working.

Chen Changzai was very happy.

So he simply stopped doing it himself.

His students did all the assembly and debugging of the hydraulic press; he only explained to them what to pay attention to.

For example, how should the damping coefficient of a hydraulic press be calculated, why should it be calculated in this way, and under what circumstances will certain variables occur?

This is just an explanation of some related issues that they might encounter in practical applications.

After his students finished assembling the hydraulic press.

They thus completed one lesson.

At this moment, Master Liu brought one over.

After Master Zhang finished forging, he handed it over to Master Liu to mill out himself, and Master Zhang also personally made the quenching die.

He handed over a gun barrel, thicker than that of a Hanyang-made gun, already drilled with a gun hole, to Chen Changzai.

Master Liu said, "Director Chen, this is the barrel of the ZB26 light machine gun, which has been annealed."

There is no rifling yet.

This die head is made according to the drawings you provided, Director Chen. It is a four-strand, right-handed die head with a winding pitch of 240 mm.

We can try it now.

"Okay, let's try it out first. This thing has the same rifling twist rate as the Hanyang Type 88 and the ZB26 Czech light machine gun."

　Thank you to all my friends who have supported me.

　　I finally finished another chapter. My brain feels swollen. I've read so much material, all of which is useless in daily life, like rifling, which is a very harsh torture device.
